D
Larger surface area speeds up reactions
Rust is an oxide so more oxygen should speed up rate of rust
Temperature also speeds up reactions
+ The humidity affects it aswell
Answer:
5.59x10^-3 moles
Explanation:
The balanced equation for the reaction is given below:
HCl + KOH —> KCl + H2O
Now we can obtain the number of mole of HCl required to produce 5.59x10^-3 moles of KCl as follow:
From the balanced equation above, 1 mole of HCl produced 1 mole of KCl.
Therefore, 5.59x10^-3 moles of HCl will also produce 5.59x10^-3 moles of KCl.
From the illustration made above, we can see evidently that 5.59x10^-3 moles of HCl is required to produce 5.59x10^-3 moles of KCl
<span>The gas phosphine (PH3) is used as a fumigant to protect stored grain and other durable produce from pests. Phosphine is generated where it is to be used by adding water to aluminum phosphide or magnesium phosphide. Give formulas for these two phosphides.
</span>Al₂P₃ + 3H₂O → 3PH₃ + Al₂O₃
MgP + H₂O → PH₃ + MgO
The correct answers are:
1. Lithium - C) Opaque solid with higher density
2. Lead - B) Malleable, soft, and shiny
3. Florine - D) Highly reactive gas
4. Krypton - A) Nonreactive gas
